My first thought is that your Coolant mixture is off. a 60/40 to 40/60 mixture of Ethylene-Glycol/Distilled Water mixture is acceptable. You can use a Hydrometer to test the Specific Gravity of your coolant to determine if it is within this range. If needed, drain your radiator and replace the coolant. A 50/50 mix is best for most environments (anywhere in the continental US). Coolant can be purchased in either predilluted mixtures (50/50 or ready-to-use) or full strength concentrate (which requires the addition of equal parts water).

have you checked the radiator cap? if the spring pressure is not great enough, this lowers the normal boiling point of the coolant, thus boiling quicker and over heating. a pretty cheap item to just replace with the age of your car. buying straight coolant is the same price as buying pre-dilluted coolant, only thing is its already mixed with de-mineralized water, more bang for your buck if you get straight coolant and pickup distilled water at cvs for pennies, save it for a later use!
